Lignin, a biopolymer obtained from agricultural/forestry residues or paper pulping
wastewater, is rich in aromatic structure, which is central to its adoption as a candidate to …

In recent years, there has been a growing interest in the application of antioxidants in food
and pharmaceuticals due to their association with beneficial health effects against numerous …

We evaluated the antioxidant and antimicrobial activity of a methanolic extract of the roots of
Arisaema jacquemontii. Antioxidant activity was determined in the 1, 1-diphenyl-2-picryl …

Numerous assays were developed to measure the antioxidant activity, but each has
limitations and the results obtained by different methods are not always comparable …

Natural phenolic compounds are abundant in the vegetable kingdom, occurring mainly as
secondary metabolites in a wide variety of chemical structures. Around 10,000 different plant …

We report on a paper-based 2, 2-diphenyl-1-(2, 4, 6-trinitrophenyl) hydrazyl (DPPH) assay
for a simple, inexpensive, low reagent and sample consumption and high throughput …

A method combining solid-liquid extraction based on ethanolic aqueous solution, cLC-DAD
and chemometrics, was performed to extract and quantify polyphenols from citrus peels. LC …

The 2, 2-diphenyl-1-picrylhydrazyl (DPPH•) radical is approaching 100 years from its
discovery in 1922 by Goldschmidt and Renn. This radical is colored and remarkably stable …

Kinetics and stoichiometry of reactions between the 2, 2-diphenyl-1-picrylhydrazyl (DPPH)
stable radical and 25 antioxidant compounds with different structure, molecular weight …

Parasitic multiscale free radical reactions of electrolytes not only deteriorate battery
performance but also cause a fire hazard. Therefore, fundamentally blocking free radical …
